Question 1.
What is the critical path in a VLSI design?
Show hintHide hint
Think about sequential operations and their impact on timing.
Question 2.
Name one technique used for critical path optimization.
Show hintHide hint
We discussed several methods during class.
3Question 3.
What does the critical path determine in a circuit?
- Minimum time required to complete a task
- Maximum power consumption
- Total area of the circuit
Show hintHide hint
Think about the longest sequence in tasks.
4Question 4.
True or False: Retiming involves changing the functionality of a circuit.
- True
- False
Show hintHide hint
Consider the definition of retiming.
Question 5.
Design a small circuit with a known critical path and then apply gate resizing and retiming to reduce its total delay. Explain your reasoning and expected results.
Show hintHide hint
Consider what components are along the critical path.
Question 6.
Discuss the implications of ignoring logic restructuring in a circuit design. What potential issues could arise with respect to timing and performance?
Show hintHide hint
Reflect on how complexity affects both speed and energy.
